Problem Statement Objective Scope Project structure

2 The Thermoelectric generator TEG used for converting human body heat energy to electrical energy. The proposed TEG was composed of a polydimethylsiloxane PDMS substrate and thermocouples. The use of PDMS provides flexibility to the TEG and low thermal conductivity that helps minimize losses in the effective heat flowing through the thermocouples. The proposed TEG was fabricated by simple dispenser printing for thermoelectric materials. The fabricated TEG was attached to the human body and generated electrical power of 50 nW when the temperature difference b etween the human body and ambient air was 7 ◦C.Jo, Kim, Kim, Kim, Kim, 2012. Sports apparel that contributes in this device is back support. The back support was frequently used for support an operator in field of manufacturing. It’s been used widely to maintain body posture to make sure an operator not easily collapse or faint. The back support will integrate with TEG and other component to absorb the heat from human body and convert it to electric energy that can used for charging an electronic devices. This project studies about design and development of portable charging station that convert heat from human body to become electric energy. It will show the capability of heat that can generate the new power source according the product requirement. Furthermore, prototyping and analysis of the FOS and safety of this product can be implemented into this project to define whereas it’s possible to generate new product that surely opens the innovation field.

1.2 Problem Statement

The exiting problem that have been discovered for the nowadays other alternative of power source. The heat from human body commonly not make sense. The waste heat of human can be one of the sources of energy that can help human for their life. The existing energy such as solar, water, and wind is the common use for life. It’s also has their own weakness. For example, solar energy need to energise when the sun 3 appear same as wind. The heat of human can be generate sort of energy such as electric energy. The limitation of it can be reduce if the human active in their life. For example, solar energy that believe will have huge long term benefit to global, has been found having a problem in consistency and reliability. If there is no sun, there is simply no power. Solar panels designed to generate electricity and the maintenance of system would be prohibitively expensive. Due to reliability, cost and low efficiency, most people unable to use it. To solve for searching the new source of energy this human heat can be harvest using the suitable devices and method.

1.3 Objective

The objectives for this project are: a To design a sport apparel armband for portable charging station. b To develop first idea concept of portable charging station.

1.4 Scope

In order to make sure the project that was carried out will be achieved the objectives stated, which is to design and development of portable charging station with sports apparel , thus the scope of the study was proposed to make sure that the project flow will be easy, regular and well organized. This project focuses on invention of portable charging station including design product, circuit design, fabrication process, and experimental of product. Moreover it will focus based on product design development. 4
